Application filed December 7, 1922. Serial No. 605,402.

This'invention relates in general to car construction and more particularly to the bodies thereof, and has especial reference to improvements in the carlines used in framing car roofs.

While this invention is illustrated as a carline especially adapted for use in the body structure of freight cars, it is to be understood that this device may be elsewhere conveniently employed, and, therefore. finds a wide field of utility for purposes other than that herein described and illustrated.

The principal objects and advantages which characterizethis invention reside in the provision, in a car body construction involving the use of metallic members, ofa carline wherein a given weight and quantity of metal or other suitable material is most advantageously employed in the production of a car body of maximum rigidity and strength, a minimum of weight, simplicity of manufacture, avoidance of waste of material, and low cost; the provision of a carline which, in itself, affords an article of manufacture which is characterized by the features of simplicity, strength, low cost of manufacture, low weight proportional to strength, and a high degree of durability; the provision of an improved carline construction which is adapt-able for employment as a component part of either the side or end plate construction of a car body; the pro vision of an improved carline construction characterized by the embodiment therein of an improved arrangement of the portions, of the carline whereby to attain a high degree of strength and rigidity at the medial portion of the carline without-employment of a great amount of metal; the provision of an improved carline characterized by the feature whereby the weight of the'carline at its medial portion and, consequently, the strain exerted by such weight, are reduced to a. minimum compatiblewith sound construction; the provision of an improved carline having a shape affording all the advantages of a truss-built beam without the attendant cost of manufacture and other dis advantages of such truss beam in order to secure the greatest strength and rigidity of the carline at its medial portion and attain the greatest resistance to all bending mo= ments and otherstresses to which the roof and the supporting carline, or carlines, may be subjected in service; and the provision of such an improvedca-rline construction having the features and advantages pointed out above, in combination with an improved anchoring means for securing the carline fixedly to the side plates of the car body.

This invention is further characterized by the provision of a carline embodying an improved end construction, that is, the ends of the carline being so constructed as to facilitate the convenient securement of the carline to the side plates; and the provision of improved securing means, hereinafter described as brackets, for attaching and reinforcing the carline and the side plates where these two elements are joined.

The foregoing and such other objects and advantages as may appear as this description proceeds are attained in one structural embodiment of this invention illustrated in the accompanying drawing, in which Figure 1 is a top plan View of a carline eniibodying the improvements of this invention and. illustrated as applied in a car construction Figure? is a fragmentary sectional view through a railway car body illustrating a roof construction embodying the improved carline of this invention;

Figure 3 is an enlarged end elevational view of the carline and one of its brackets;

Figure 4 is an enlarged vertical sectional View taken on the line 4t 4 of Figure 2, looking in the direction indicated by the arrows;

Figure 5 is an elevational view of a detail;

Figure 6 is fragmentary sectional. View of modified form; and

Figure 7 is a perspective view of a further modified form of a part of this invention.

Referring first, more particularly to F igures 1 and 2 of the drawing, the device of this invention conveniently is formed from a sheet of metal of suitable thickness and rigidity, which sheet may be rectangular, or any other convenient shape, and formed under pressure, or in any other suitable manner, to provide a flat vertical web 5, the upper portion of said web being formed to 'provide a continuous lateral flange 6, the forming of such flange being of uniform width and extending in a fixed" horizontal plane from end to end of the carline. The flange 12 is provided-with en tended portions beyond the end edges 13-13 of the vertical web and said extensions are bent conveniently upwardly at 1 1 and 15 and apertured at 16 to receive boltsor' other fastening elements, indicated at 18, which pass transversely through the side plates indicated at 19 and 20.

The top flange 6 pression surface or flange 12 forms in effect a tension surface or'shelf, and the top flange hasextending end portions 21'and 22, (Figures l and 2) slightly bent downwardly to engage and seat upon the upper outwardly inclined surfaces of the side plates 19 and 20, respectively.

The inclined portions 8 and 9 of the flange G'are of gradually increasing area i from the medial fiat portioi'i 7 toward the fiatport-ions 10 and 11, as best seen in Figure 1, this being accomplished by cutting or otherwise removing the metal of the flange 6 along the lines 23 and 2 1, Figure 1.

' It will thus be seen that the vertical web takes aform which is of gradually decreasing' depth from the medial toward the end portions of the car and that the medial portion of the carline, which must possess a high degree of strength and rigidity, is given these qualities by virtue of the depth of the web at the medial; portion. Furthcrmore, the removal of the surplus metal of the flange 6 along the lines 2?; and 24 affords the necessary strength with the advantage of permitting a reduction in weight witl'iout sacrificing such strength. It will be observed further that due to the form of the carline the sum of the widths of the flanges 6, 12', and the web, transversely of the carline will be generally substantially the same, throughout the length of thecarline. g

The arrangement of the inclined portions 2 8 and 9 and the disposition of the extending portions21' and 22'is such that the desired sloping of the roof boards is conven'iently attained.

In applying thereof, the ridge pole 25 is conveniently secured to thefiat portion '7 of the'compression'surface in any suitable manner, such as bybolt-s' or the like, and the roof} comprising the two sections 26 'and 27','is secured to the ridge pole and sup ported on and secured to the purlins 28-28,

forms in effect a co1n-' shelf and the bottom.

which latter are in turn supported upon and secured to the portions 8 and 9 of the compression flange.

The roof boards extend out over the extensions 21 and 22 and may be secured in anydesired manner to-the side plates.

For reinforcing and for fixedly attaching the ends of the carline to the side plates,

.injaddition to the lugs or upwardly bent extensions l t and 15, I provide an improved bracket which, as best seen in Figure 5, is formed conveniently of a blank of metal to form a body portion 29,'cut-and formed to afford an end lug 31 and a flange 32, said flange lying in angularly. related The lug 31' isbent laterally of the" When the bracket is properlyformed, and

prior to the installation of the car line, the lug 31, by virtueof the-aperture therein, is secured by means of a rivet 37 to the end portion of the web 5, and theflan'gc 32 is similarly secured by rivets -38 to the under surface of the compression flange, the.ex-- F tensions 21 aud-22 lying beyond the body 29 of the bracket, as best seen in' Figure 2.

The body of the bracket is provided with .an

aperture 39, through whi'ch:said' aperture and the side plate, a bolt ll) may pass for fixedly securing the bracket to the. side plate.

Referring now to Figure 6, the structure here'niay be siiibstantially identical with that hereinbefore described, with the additional feature of the members 21 and 22", which lat-' ter are extended over the side'plates, and bent downward as at 23 along the outer-surfaces of the side plates. r

-Referring to Figure 7, 21 modified form of the bracket'is shown, the variation here over that previously V described residing particularly-in the mode of construction of the bracket. In this form of the bracket the-element is formed from a plain sheet of metalof the required size and rigidity,-and may conveniently, while hot, be bent 'to' form the body 29 flahge 32? and end lug 81, the blank of metal being preferably of sufficient length, and after formation into a box like shape, out along the dotted line AB to thus. produce two brackets. I find that the metal,

'while hot, will readily, under pressure, form the end lug, body and flange of the bracket integral, thereby affording an article of great strength and rigidity and which may be manufactured at low cost;

From the foregoing description it will be observed that due. to the formationof the car'line, it is possessed of a high degree of strength at its medial portion at which the Hit) than

greatest strain more often occurs, and that due to the construction of the bracket, and the overlapping extensions 21 and 22, but two bolts are required for adequate secure.- ment of the carline to the side plates. Thus, I am not only enabled to materially reduce the cost of manufacture, reduce the weight without a loss of strength, but also provide a device of the character described which may be conveniently installed.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is:
